本文实例讲述了php实现singleton()单例模式的方法。分享给大家供大家参考。具体实现方法如下:

common.php文件如下:

复制代码 代码如下:
class CC 

private static $ins; 
public static function singleton() 
 { 
         if (!isset(self::$ins)){ 
            $c = __CLASS__; 
            self::$ins = new $c; 
         } 
         return self::$ins; 
    } 
public function EventResult($Id) 

return $Id; 


?>

index.php文件如下:
复制代码 代码如下:
 
     
        测试 
         
     
     
require 'common.php'; 
$objCC=CC::singleton(); 
$r=$objCC->EventResult(7); 
print_r($objCC); 
echo $r.""; 
?> 

希望本文所述对大家的PHP程序设计有所帮助。
